Welcome to the spider page! On this page you will learn about how
spiders communicate, what they look like, what they eat, where they
live, and what they do during the day and night. Did you know
that spiders are not insects? They are different than insects
because they have eight legs instead of six, no antennae, and have
two major body parts instead of three.
spiders communicate visually. For example, did you know that one way a
female spider communicates
is by attracting a male by dancing?
Once a male finds a female it shows off its colorful legs
by thumping them on the ground and then starts waving them in the
Also, spiders with well-developed eyes have a very complex mating
display that uses bright color patterns.
also communicate through touch. When
a spider rams his front legs into the ground, it vibrates its
body and once it shakes the body the vibration moves to the ground. Next the female will feel the vibration and maybe she will
mate with the male.
Spiders also bite when they think they can't escape.
know that some spiders have four eyes but most have eight?
Most spiders are very colorful and camouflaged with plants and
holes. A tarantula has little hairs all over its body.
There are two main parts of the spider’s body which include the cephalothorax
(which is a fused head and thorax) and the abdomen.
Ususally the cephalothorax and abdomen are connected to each other with
a waist that is actually the last part of the cephalothorax.
Spiders also have special appendages called spinnerets on their
abdomens. These make the silk that spiders use to create their

also have two pedipalps (or palps) located next to their
mouths. These leg-like structures help them eat their food.
about everywhere in the world. In
houses, woods, and anywhere else where a spider can hide. In a house
they can hide under beds, in closets, and in small corners. In the woods
they can hide in logs, trees, and bird nests.
eat many different kinds of foods. They are usually carnivorous and
feed only on living prey. They like to eat insects, but some
spiders have also been known to eat small mammals, fish, and birds.
spiders catch their food by building webs to trap insects. Their
webs are made out of spider silk. The silk is a thin protein
strand made by the spinnerets
you know that jumping spiders do not make a web to catch their
food? Instead, they jump and leap to catch their prey, but they have to
have amazing eyesight to catch it at the right time. Even though
they are harmless to humans they eat flies and other insect pests. Almost all spiders eat those too.
reproduce by making eggs. When
a female spider has eggs to watch over, she hides them in a sac, so she
can keep track of them. A female spider can lay up to 100 or more
eggs. When all of them hatch they start crawling all over the area
that they hatched from.
Other Interesting Facts |
- The study of
spiders is known as called arachnology.
For its weight, spider
silk is thought to be five times as strong as steel!
discovered over 38,000 species of spiders. Most scientists believe
there are actually more than 200,000 different species, but because they
hide, most have not been found.
Only 40 species of
spiders are thought to be dangerous to humans.
A single spider can spin
many different kinds of silk.
jumping spiders are mostly active during the day. They find food to
eat and sometimes find a mate to mate with.
Also most spiders are active
during the night. They sneak up on their prey or just go on a walk in
